class GMII(col=False, cs=False, tx_er=False)[source]#

Bases: Port

Gigabit Media Independent Interface (GMII) Bundle Generator see https://en.wikipedia.org/wiki/Media-independent_interface#GMII

Parameters:

col – Include collision line
cs – Include carrier sense line
tx_er – Include transmit error line

txd = (Port(), Port(), Port(), Port(), Port(), Port(), Port(), Port())#: Transmit data bus

rxd = (Port(), Port(), Port(), Port(), Port(), Port(), Port(), Port())#: Receive data bus

gtx_clk = Port()#: Gigabit Clock (125MHz)

tx_clk = Port()#: Transmit clock for 10/100 MBit

tx_en = Port()#: Transmit enable

rx_clk = Port()#: Receive clock line

rx_dv = Port()#: Receive data valid line

rx_er = Port()#: Receive error line

col: Port | None = None#: Collision

cs: Port | None = None#: Carrier Sense

tx_er: Port | None = None#: Transmit Error
